The Blood Angels and Black Templars pursued the Orks and Alpha Legionnaires, and finally got a confrontation between them in a rocky region of the area. The Greater Daemon of Ork killed the Grand Master of the Grey Knights, but was in turn killed by the Grey Knight Terminators. It was a close call, with the battle switching from a certain victory for Chaos and Orks in the beginning to a minor victory for the imperials.
After this defeat Abaddon returned to the Eye of Terror to consolidate his forces gathering there. His forces on Rhoie and Messen dug in, as did the imperials during the events that would later be known as the Eye of Terror campaign.
